Genome

Genome Characteristics

1. Stores information in a stable form: The genome of every organism stores information that provides a blueprint to create its characteristics.

2. Provides continuity from generation to generation: The genome is copied and transmitted from generation to generation.

3. Acts as an instrument of evolutionary change: Every now and then, the genome undergoes a mutation that may alter the characteristics of an organism. In addition, a genome may acquire new genes by horizontal gene transfer. The accumulation of such changes from generation to generation produces the evolutionary changes that alter species and produce new species.

Proteomes

Is the entire protein complement of a cell or organism. Proteins are largely responsible for the structure and function of cells and complete organisms. All of the proteins that a cell or organism can make.

Hypothesis

1. Proposed explanation for a natural phenomenon
2. Educated guess based on previous observations or experimental studies
3. Hypothesis must make predictions that can shown to be correct or incorrect (must be falsifiable)
4. Additional observations or experiments support or reject a hypothesis
5. A hypothesis is never absolutely proven
6. We may not have found the true explanation for a phenomenon.
